The patented ATI Super Damper is the only crankshaft
damper designed exclusively for high performance Chrysler,
Dodge and Mopar Engines - including the new HEMI!
Whether you race or just drive on the street, ATI's
harmonic balancers are the perfect choice.

Eliminates torsional crankshaft vibrations

Exceeds SFI 18.1 specs

Black zinc chromate finished

OEM equipment on 392 Mopar Crate Engines

Tunable, rebuildable, and extremely efficient at
ALL RPM

Laser engraved 360° timing marks

Inner and outer shells are available in aluminum or
steel, and contain a steel inertia weight. This inertia
weight has six (2-ring design) or eight (3-ring design)
computer machined grooves to retain the proper durometer
O-rings (dyno tested for each application).

Hubs are dimensioned to clear the stock
cast-in timing tab on MOST applications.
Due to changes by the manufacturer over
time, the tab MAY need to be ground
and re-welded. The damper face for
pulley mounting will be forward of the
OEM location by .150” for 2-ring internal
balance, .450” for 3-ring int. balance,
.750” for 3-ring ext. balance. Hubs may
be shortened by the listed amount for internal
balance & by .600” (.150” fwd of OEM) on
ext. balance if tab is cleared. 2-ring int.
balance can be installed in OEM location
with minor clearancing of timing tab & retain
OE timing mark.

Customer must cut and reweld the stock
timing tab. This damper is OEM location.

Part #918442E-99 shell is used. 99 durometer rings are used with driver’s side timing.

How to read
this chart

Locate the correct manufacturer's chart

Choose the specific engine application listed
down the left side of the chart

Determine if the damper needs to be internally
or externally balanced ( external balance dampers are constructed
of steel only). Black bars that extend horizontally across the
entire chart designate these sections

Determine if you need steel or aluminum shells.
Labels for this information are listed across the top of the chart
in columns 2 and 3.

Once you have determined the shell material,
you need to find the outside diameter (OD) of the desired steel
or aluminum shell. Then choose between 2 or 3 rings and the desired
weight of the damper.

From the far right section of the chart, select
either a steel or aluminum hub for your desired engine application.
To determine the correct damper assembly part number that intersects
is the correct damper assembly.

Assembly part numbers that are color coded
correspond to the pulley mount bolt pattern listed near the top
of the charts.
